Title:
INDIRECT INJECTION GAS ENGINE WITH FUEL COOLER
Document Type and Number:
Japanese Patent JP3663949
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the durability of fuel injectors by cooling fuel gas to be supplied to auxiliary chambers with fuel coolers and holding its pressure always constant despite of variations in its flow rate so that a proper fuel-gas flow rate is fed to compression chambers.
SOLUTION: The indirect injection gas engine has an auxiliary chamber 2 formed in a piston 15, and a compression chamber 8 formed in a combustion chamber member 10 placed in a cylinder head 3. A fuel injector 5 has nozzle holes 16 adapted to open into the auxiliary chamber 2 in the piston 15 brought near the top dead center. Fuel gas compressed by a fuel pump 28 is cooled by a fuel cooler 47, regulated in temperature depending on variations in its flow rate and kept at a prescribed pressure before fed into the compression chamber 8, wherein it is boosted up by a compression piston 21 before injected into the auxiliary chamber 2 via the nozzle holes 16.
